無刷直流電動機是采用半導體開關器件來實現(xiàn)電子換向的，即用電子開關器件代替?zhèn)鹘y(tǒng)的接觸式換向器和電刷。它具有可靠性高、無換向火花、機械噪聲低等優(yōu)點，廣泛應用于**錄音座、錄像機、電子儀器及自動化辦公設備中。無刷直流電動機由永磁體轉子、多極繞組定子、位置傳感器等組成。位置傳感按轉子位置的變化，沿著一定次序對定子繞組的電流進行換流（即檢測轉子磁極相對定子繞組的位置，并在確定的位置處產生位置傳感信號，經信號轉換電路處理后去控制功率開關電路，按一定的邏輯關系進行繞組電流切換）。定子繞組的工作電壓由位置傳感器輸出控制的電子開關電路提供。位置傳感器有磁敏式、光電式和電磁式三種類型。采用磁敏式位置傳感器的無刷直流電動機，其磁敏傳感器件（例如霍爾元件、磁敏二極管、磁敏詁極管、磁敏電阻器或**集成電路等）裝在定子組件上，用來檢測永磁體、轉子旋轉時產生的磁場變化。江蘇電機報價</p><p
